Well, today 28 august 2012.
With the new version of Guild Wars 2 launcher, looks to be working nice for me.
We still have the large black border but at least the transparent window inside that black window is now visible.
My understanding of the issue is: The launcher have two layers.
A transparent background layer. The other layer is the dynamic window that showing up your login and password and download progress.
The bug is that the dynamic layer window become hidden behind the background layer window.
Now, the transparent background layer still not showing up correctly but they fixed the dynamic window so you can now interact with it correctly in wine.
I don't know how they made the layer but it is not compatible with wine.
To me this bug looks very similar to the Diablo (first Diablo) game bug about the game menu being covered with a black square.
